Application filedAugust 26, 1914. Serial No. 858,685.

To all whom it may concern:

Be it known that I, VVILLIAM H. BAGBY, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Nutcrackers; and I do hereby declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in nut crackers, and has for an object to provide a nut cracker which will be simple in construction and operation and constituted of a minimum of parts, each of which will be economical of manufacture and readily assembled to form the nut cracker.

It is another object of the present invention to provide an improved nut cracker which will be effective in operation and under control of the operator to apply to the nut any degree of pressure required for effecting the cracking of the shell thereof without destroying the structure of the meat.

A further object of the invention resides in providing an improved nut cracker which will be efiicient in operation to the end that large quantities of nuts may be cracked in a minimum of time, whereby to decrease the cost of the operation of the previous methods.

With these and other objects in view the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claim.

In the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views: Figure 1 is a perspective view of a nut cracker constructed in accordance with the present invention. Fig. 2-is a side elevational view, partly in section, of the same; and Fig. 3 is a cross sectional View taken on the line 3-3 of Fig. 1.

Referring more particularly to the drawings, wherein one embodiment of the invention is illustrated, 1 designates a frame stamped or cast of metal, or produced in any desired manner of other suitable material; and the same is constructed with a clamp 2 operated by a set screw 3 whereby same freely rotates.

the device may beattached to the edge of a table or other support, asillustrated in Fig. 1. The frame 1 is provided at one end thereof with an upstanding and curved arm i, to the outer free end of which is secured a fixed jaw 5, extending parallel with the longitudinal center of the frame; The opposite end of the frame is constructed with a post 6 for supporting a bearing sleeve 7, in axial alinement with the fixed jaw 5, and in the bearing sleeve 7 is produced a spiral groove 8. J ournaled in the bearing sleeve 7 is a plunger 9 arranged to be rotated by a handle 10 connected to the outer end thereof.

The rotary motion imparted by the handle 10 to the plunger 9 is adapted to be converted to reciprocate the plunger, and to this end the plunger 9 is provided with a roller 11 secured to the same by a screw or other suitable means 12, about which the The roller 11 travels in the spiral groove 8 formed in the sleeve 7, and cooperates with the groove to reciprocate the plunger when the handle 10 is actuated. To the inner end of the plunger 9 is swivelly connected a movable jaw 13, through a screw 14 threaded into the plunger, and upon which the jaw 13 is free to revolve.

In operation the nut to be cracked is positioned within the fixed jaw 5, and the handle 10 grasped and rotated in the direction of the arrow in Fig. 1, whereupon the movable jaw 13 will advance and grasp the opposite end of the nut, securely holding same between the jaws. Any desired pressure can be brought, to bear upon the nut, as

required for breaking the shell of the latter,

without afiecting the meat; and after the operation of cracking, the handle 10 may be released and the same will fall by gravity and cause the movable jaw 13 to retreat and release the nut, which will thereupon fall upon the table or other support or receptacle provided to receive the same.

It will be understood, that, while the plunger 9 receives a rotary motion from the handle 10, the jaw 13, after being brought to position to clamp the nut, will not receive this rotary motion due to the screw 14, which will revolve freely within the jaw 13 and permit the same to exert a direct pressure upon the nut without rotating.

I have illustrated and described preferred and satisfactory constructions, but obviously changes could be made in the herein without departing from the spirit of my inc vention.

I claim:

In a nut cracker of the character de-c scribed, the combination of a frame, an arm formed at one end of said frame, a fixed jaw supported onsaid varm, a post formed at the opposite end of said frame, a cylindricalbearing supported on said post parallel with said frame and coaxial with said fixed jaw, said bearing being provided with a spiral slot formed in the upper longitudinal portion of the same, a plunger mounted for reciprocation and rotation in said cylindrical bearing, means mounted on said plunger and operating in the spiral slot in said bearing for reciprocating the plunger when rotated v a movable jaw swivelly connected to the inner en'd'of said plunger and arranged to cooperate with said fixed jaw to crack the nuts therebetween, and a handle mounted in WILLIAM H.
